Red Umber

A burnt umber that is so warm it takes on a true reddish quality. Almost a mid-step between Burnt Umber and Burnt Sienna.
 
Brown Pink #1484 Brown Pink
Hydrated Synthetic Iron Oxide - PR101
Semi-Transparent / Lightfast Rating 1 - Excellent
    
Similar to Stil de Grain in history and chemistry but with a beautiful, transparent, cordovan color. Its beauty is best seen when used transparently. Absolutely permanent.
 
Cyprus Orange #1512 Cyprus Orange
Natural Iron Oxide - PBr7
Dipyrrolopyrrol - PO73
Semi-Opaque / Lightfast Rating 1 - Excellent
Not unlike Raw Sienna, but with surprisingly clear, transparent, orange undertones. You can almost feel the warm Mediterranean sun in this color.
 
Brown Umber
#1631 Brown Umber
Natural Iron Oxide - PBr7
Semi-Opaque / Lightfast Rating 1 - Excellent
The warmest raw umber we have ever seen - Not as red or as finely ground as the Burnt Umber.
 
Dutch Brown #1494 Dutch Brown
Synthetic Iron Oxide - PBr6
Semi-Transparent / Lightfast Rating 1 - Excellent
   
Very close to Cassel Earth--but absolutely permanent. In mixing if you find umbers to be too "smoky or atmospheric", you will find this to be very crisp and rich. This is also a very versatile pigment--we have seen it used to create viscous, tarry looking surfaces as well as very lustrous, sleek rich browns like fine mink fur.

#1641 Turkey Umber
Natural Iron Oxide - PBr7
Semi-Opaque / Lightfast Rating 1 - Excellent
Phthalocyanine Green - PG7
Very briny with a pronounced greenish tone.
 
Bohemian Green Earth

Natural Iron Oxide - PG23

Another natural Terra Verte but cooler than our Italian and also stronger in tinting and covering strength.
 
Brown Ochre
#1561 Brown Ochre
Natural Iron Oxide - PBr7

Very earthy, extra-deep, yellow ochre - so deep we call it brown.

Natural Iron Oxide - PR102
Opaque / Lightfast Rating 1 - Excellent

Natural Iron Oxide - PR102

A dense earthy ochre - more violet than the red ochre - with an interesting liverish quality.

VERY POOR LIGHTFASTNESS
 
Mars Black #1792  German Earth
Natural Iron Oxide - PBlk11
Opaque / Lightfast Rating 1 - Excellent
One of the most versatile blacks we've encountered. When used straight, it is very much like a traditional Cassell Earth or Van Dyke Brown, but when white is added ti cools down and becomes bluish - almost moonstone-like. Dries with a soft matte surface.
